Model the front hub

- [Instructor] Our next mission is to model a front hub,…which is shown here with this red spline.…What I need to do is hide some of this information…that we see on the screen right now.…I'll type layiso, Enter,…and click on this object and isolate everything else.…Now I'd like to revolve this around the central axis.…I'll reset the coordinate system, ucs, Enter, Enter…so that the blue axis is the one that goes up and down.…

And then I'll create a solid with the Revolve command.…Select this object, Enter.…And click these two endpoints to establish the axis.…Press Enter, and then…we will choose not to erase the defining object.…However this object is still on the 2D layer,…so it's called FrontHub.…Let's go ahead and create a new 3D layer from that.…Called -FrontHub.…

And I will change the color to green…and set this layer current.…And then I'm going to change…the layer assignment of this object…by going over to Properties and changing the layer…to the 3D equivalent.…Now we need to cut holes in these flanges,…much like we did for the rear hub on the transmission.…

You can model almost any form imaginable with the AutoCAD 3D toolsets. In this project-based course, Scott Onstott teaches you the techniques required to solve complex modeling challenges in AutoCAD, while focusing on an innovative ebike design. Learn how to create each 3D component of the bicycle model, including its frame, belt-tensioner mechanism, drivetrain, power components, brakes, wheels, axels, hubs, spokes, handlebars, and even the bicycle seat. The techniques (which can be applied to other mechanical models) cover extruding profiles, lofting 2D cross sections, revolving profiles around an axis, filleting edges, smoothing mesh objects, sculpting complex NURBS surfaces, and much more.
